## What it is
A Node.js middleware library for proxying HTTP requests, wrapping the httpxy proxy engine in a simple one-liner API. It integrates with connect-compatible servers such as Express, Next.js, Hono, Fastify, and Polka, with support for WebSockets and path filtering.

## Use cases
- proxy /api requests to a backend server during development
- add a reverse proxy to an express app
- avoid CORS issues by proxying frontend API calls
- proxy websocket connections through a node server
- route specific paths to different backend services
- set up a dev server proxy for next.js

## When to choose
- you need request proxying inside a connect/express/next.js middleware stack
- you want a simple, well-maintained reverse proxy with path filtering and WebSocket support
- you need to bypass CORS in local development

## When to avoid
- you need a full standalone reverse proxy server rather than middleware (use nginx or Caddy)
- your app does not run on a connect-compatible Node.js server
- you need advanced load balancing or TLS termination features

## Facets
- artifact type: library
- maturity: stable
- function: middleware, proxy, http-server, websocket, routing
- domain: web-development, backend, apis, developer-tools
- platform: cross-platform
- tags: reverse-proxy, express, nextjs, connect, hono, fastify, cors, dev-server, nodejs
